This is not a thread about me asking for help, more so opening the door to help others and provide general guidance with GPS issues on Lollipop.
This past weekend, I flashed back to ZV4 from ZV6. I rooted through Stump Root, installed TWRP, took a backup, and flashed two different Lollipop ROMs. I tried CM first, but am now working with Illusion as the SMS button was broke. GPS would not work no matter the fix on any Google Play Apps, be it a gps.conf changer or an AGPS manager. So there is the back story of what exactly I did, and now I will outline what I did to get GPS working.
I took current backup of Illusion and restored from backup to my stock ZV4 ROM. Lo and behold, getting into the ROM -- I found that GPS was disabled. There was also a secondary "enhanced" GPS option in the ROM I enabled from the same screen in the Location settings menu. (if anyone is still on a stock ROM, can you check for the name of that option?). I also enabled that option. I used "GPS Test" from the Google Play Store and was able to get plenty of satellite fixes -- "3D Fix."
I then rebooted to recovery, restored to the Lollipop ROM -- and GPS worked just fine. This is fairly odd, and we used this method to get GPS to work back in the OG Samsung Epic 4G days. I am wondering if its something that the Stock Rom and firmware can do -- aka turn on GPS, that Lollipop can't actually initiate and toggle. I'm sure Lollipop can "turn it off", but I am not terribly sure of this at the moment.
Anyways, I hope this helps someone out.
OMG thank you! I almost gave up on L for now because no rom I tried would give me a GPS fix. The locating icon only even appeared in the status bar for a few seconds and went away. I restored my stock nand, enabled high accuracy (I usually leave it in battery save unless I'm actually using it), flashed back to L, and bam, instant lock.

No problem. Glad I could help.
I can't, for the life of me, get this to work. I've tried instructions to the t, still no GPS on Illusion.

This has been a long standing fix, but again confirmed working for me. Brand new VS985 (Verizon LGG3 Warranty Replacement). Had booted the phone to register the new sim card and immediately rooted, Bumped, wipe and flashed Illusion 5.0. Tried maps the next day, GPS apps, etc, NOTHING would work..
Backed up that install in TWRP, loaded up Jasmine 4.0, booted in, turned on GPS, downloaded a GPS app, got a lock, immediately loaded TWRP, wiped 3x, restored my Illusion backup, booted it up, loaded my GPS app, and within 5 seconds it found GPS and locked in.
I can't claim to know why the stock rom would make any diff on turning on GPS, locking in, etc when a rom that does similar stuff and what googles phones are primarily based off of don't work.
This worked though and I'm happy!
Hey I have the same issue and tried this workaround twice, but still can't get GPS on lollipop...

I also still have the issue, and can no longer get a GPS lock on 4.4.2 ROMs after having flashed lollipop
I spent hours looking for a solution on this that would not imply flashing another ROM.
What fixed it for me was updating the gps.conf file with a proper NTP server more suitable for your zone.
The easiest way to do this is using FasterGPS app. You need root, of course. But works very well.
Didn't work for me.

I tried this method but it did not work for me. I'm hoping to figure this out without re-installing stock firmware.
Yes gps is not working on lollipop roms. I flashed 2 different lollipop roms, and neither gps is working. I restore my previous kitkat version copied the gps.conf file to my sd card, reflashed the lollipop rom and then I replaced the gps.conf file with the one from kitkat. It works. I updated the rom and the gps won't work again. I replaced it again with the gps.conf from kitkat, gps works fine again.

Sir,
I am from Pakistan. i have sprint lg g3 ls990 cell phone. I am using 3g cellular network. But when i enable data it always shows Edge not 3g. I switched network mode to cdma/ wcdma from settings menu but nothing. I flash several roms but no result.
Now i am on cloudy g3 2.5. But there is no change in my data service. I am still on edge data mode.
Any one help me what can i do to switch to cdma/ 3g?????
Thanks and waiting some support from u people.
Regards

Flash your stock firmware using .tot not kdz file,but you need another lg flash tool that uses .tot and dll files,just search on google,or use files from this site lgg3root i just did that after trying several stock/custom firmware/gpsconfig files

I currently have an issue with no GPS under cleanrom ace 4.2.5; does anyone know of a fix ? Is this a common issue on verizon?
Also can I reflash 4.2.5 to change options without wiping the phone ?

The answer is within the cleanrom forum. you have to backup, flash to another rom, get lock, reflash back.
people have said that gps test & fix in the appstore can fix the issue too
Odd I searched the cleanrom forums first but didn't see it; also did google searches; but that is what I ended up doing to fix the problem. I restored the stock verizon rom (which I saved before flashing cleanrom) and now gps works !! no clue why. 'gps fix' and similar aps on the playstore did not help at all; they merely confirmed that i had no satelites. (gps was not working).

The answer is in the cleanrom forum. Maybe not the one you were looking in, though. What you did is pretty much the solution. You should have made a nandroid and reflashed the stock rom (or working rom like beans) then restore the nandroid after getting a lock.
As far as that playstore app, I said that someone has claimed that it has worked. I personally haven't tried it/had no issues with cleanrom and GPS>
Alright guys, this is gonna be kinda long so get ready. I was running stock 4.4.2 NEW and I saw that there was a way to get GPE 4.4.3 and 4.4.4 rom working on the s4. I followed all the instructions on RickGrimes's post and wifi didn't work. Not and big deal. I couldn't soft reboot, so I tried flashing gogolies nc2 wifi fix and this modem worked. I then tried to update to 4.4.4, also following the instructions and the wifi didn't work once again. I flashed gogolies nc2 wifi fix again but it did not work. I also realized that I had no service at all and that I couldn't send or receive any messages or calls. So I did the safe thing and used Odin to get back to stock. I am currently running stock but the service is still terrible in places where I usually get great signal. Also, my wifi strength seemed to go down from what it usually is. Another issue is that my contacts that were backed up in backup assistant aren't there anymore at all. I generally know what I'm doing when it comes to this stuff but for some reason I have no idea how to resolve these issues. Any help will be appreciated.

The easiest way to fix your phone or any phone for this matter is always to download and flash the stock tar file of whatever version of Android you were last on in Odin.
Then visit towelroot.com in your browser on your phone and root it again. (Don't forget to enable usb debugging first)

I wound up going back to stock 4.4.2 via Odin, but the problem still persisted. I figured out the my network settings were changed to Global instead of CDMa/LTE. Changed it back and all is well! Thank you though!
Would like this thread to be a single thread for all the modem/wifi issues. I see many people(including myself) cluttering up Rom threads with these issues. There are so many different variations of our issues and what bootloader we have vs. how we are rooted.
I'm on original MDK bootloader using TWRP as my recover and have the Verizon S4. I've never had any issues with wifi or bluetooth until I got into HyperDrive Rom around RLS 16. My issues started with no wifi or bluetooth but my hotspot would work. Then I got to the NC2/NC5 modems and lost bluetooth and wifi. The only way I can get everything to work is go back to the retail MDK modem file. Seems all the NC5 and NC2 fixes are for Safestrap. When I install those it messes with my HLOS and I lose sound and have other issues.
So, does anyone have any suggestions on where to start from?
Update: Another issue that I see, is under settings, under my hotspot option, it has "error". Never seen that before.

Very similar problem, if not the exact same problem. I had been fighting it since Hyperdrive 16 like you as well. I just fixed it about an hour ago with the help of some other people on the forums. Here is what I did to fix the problem. I started with the files here:
http://forum.xda-developers.com/showthread.php?t=2487298
I flashed the "MDK Modem+NONHLOS" file in TWRP and booted into the ROM to confirm that everything was working with the radios. Then flashed the standard retail NC5 modem (modem only file) from TWRP and booted into the ROM. All of my radios are working better than ever. I finally have fully functional WIFI and Bluetooth on Hyperdrive 18.1. I can't explain why this works yet; as I just discovered it and haven't had time to research yet. Hope this helps you out. I know half a dozen other people in the forums that I need to share this info with as well.

I have; both work very well. Why do you ask?
The last few times that I have gotten my wifi to work, once I tried my hotspot app then went back to try wifi, it was broken. When I hit my wifi quick launch button my hotspot will turn on.
So I finally Rooted my S4; Stock root with the towelroot method. And now the bluetooth won't turn on.
Ok, I was stock rooted to allow for wifi hotspot. Once I started getting the latest OTA from VZW I decided to try to go back to stock to accept the OTA. I went through all the YouTube video's and loaded the LG software but my phone would never sync to the LG suite software. I ended up giving up and just kept pushing the OTA off. It got so bad that I decided last night to install a recovery and then flash an unofficial CWM rom. So this morning it was working fine and then all of the sudden, I lost VZW data. Couldn't get any signal. So I decided to try to flash the Official Cyanogenmod 11. That blew up during the setup and gave me an error that it could not find any cellular service. I wiped the phone and tried to restore the backup I made of my stock rom with the recovery on it. I made the backup the second the recovery was finished. It's giving me an MD5 error?? I've tried this multiple times with the same result. So, I then decide to flash one of the two roms (unofficial & official) back to see if I can get the phone working again. No such luck.... It keeps trying to set up my "cellular service" and just runs. Nothing ever finishes. I'm really worried at this point. I would be perfectly fine to flash a Verizon image and go back to stock. But I can't seem to find out how to do this or where to find the file. Please help me.. I'm getting desperate.
Edit: I tired to flash the Unofficial Rom again and this time it seems to be working. I would still rather just go back to stock though. If anyone can point me to the correct place I'd be very appreciative.
Thanks
Dave

Here is a link to flash back to stock: http://forum.xda-developers.com/verizon-lg-g3/general/guide-flash-to-stock-10b-kdz-method-t2928140
I know you wanted to take the OTA, but why not download one of the stock based 11c ROM's, like Jasmine 3.0? That way you'll still get the latest version(11c) but you won't lose root and recovery. The OTA patches root, so no recovery either. Here's a link for Jasmine 3.0 stock based 11c if you want to try it: http://forum.xda-developers.com/verizon-lg-g3/development/rom-jasminerom-v1-0-t2904641
Also, there has been issues with data on the CM builds. It seems pretty common right now. Check the CM threads for more info on that. I believe there is a command people have been entering(killall rild in terminal emulator) to get data back, but it seems 50/50 that it'll work.

Hey thanks a lot for your reply. I understand what you're saying with going back to stock. My issues with flashing custom Roms is that I have to have my phone work 100%. I've been flashing since the original Droid Incredible. And I've NEVER found a Rom that didn't have minor glitches and issues. Usually those issues affect my daily routine. I'll give Jasmine3.0 a shot and if it works I might just keep it. If not i'll just suffer through VZW's BS! Anyway, really appreciate your input.

Glad to help. I'm with you on the 100% functionality too, so that is why I'm on Jasmine 3.0. Don't get me wrong, I love custom ROMs and all the work the devs do, but until all the kinks are worked out I'd rather be stock.
Also, I'm not trying to advertise anything, but flashing the skydragon kernel into Jasmine has helped the speed/lag and battery life as well. Its worth a try - but it only works on stock/non-AOSP based ROMs. If you try it though, also download the stock 11c kernel that the OP put in the thread just in case you have issues. I don't have the link handy, but the kernel is located in the "original android development" thread. Peace

To be honest, I'm not sure what drivers I was using. I did a Google search for LG suite and found the closest version I could find. They didn't have the VS985, Only P985. So that might have had something to do with it.

Modem is the radio. Some people reported better signal strength on the 11c modem versus the 10b modem, but I didn't notice too much of a difference myself.

You know, it's really odd but the last few weeks my phone's signal has dropped. I listen to Sirius through my phone during the day at work. And I've always received 1 to 2 bars of 4g. But the last few weeks, It's dropped to about 2 to 3 bars of 3G. I thought maybe VZW was secretly throttling me. But maybe it's the updated Radio?

It's possible the modem could've been causing problems. Is 11c better or worse for you? And its also possible big red was throttling you too. That seems like something they'd do.
If you use/like xposed framework G3 tweaksbox is a good app to get for customizing your phone a little bit. And greenify and amplify are good xposed apps that help your battery life a whole lot. They are worth checking out in the play store.
I have been trying out a few Lollipop ROMS over the last couple of weeks. The last 2 ROMS I have tried my GPS would not work at all. Yesterday I reloaded a backup that I know had a working GPS (Illusion 6.0), and GPS still does not work. Now I believe this is an issue with my phone. Is there a fix to get my GPS working again?
Several things to try:
1. GPS Status in the Play Store. Reset and re-download the A-GPS data.
2. Put a stock ROM on the phone and get a GPS lock and then go back to your other ROM.
3. Number 2 and then number 1 under stock before going back to your other ROM.

I did all 3 steps, I used JasmineROM 4.0 as my stock ROM. I was unable to get a GPS lock. Does this mean the GPS sensor has gone bad?

Are you saying you can't even get a GPS lock under a stock ROM? Maybe you should try using the LG Mobile 2014 tool to flash the 12B KDZ and verify that you can't get it working under 100% completely official stock. Try the GPS Status tool under completely stock and reset and re-download the A-GPS data. If that doesn't work, I give up.
I wouldn't assume what it means, there's too many variables no matter what.
Id say there is a probability if u cant get a lock with any of the above mentioned methods if offical stock doesnt work u can rule out a software issue
